METHOD OF CONTROLLING PROCESS OF COPOLYMERIZATION OF ACRYLYL M Russian patent published in 1995 - IPC

FIELD: chemical technology process control. SUBSTANCE: method comprises steps of successive metering of monomers and dissolvers. First dose of an initiator, mixed with the dissolvers, had been introduced, agitation and heating of a reaction mixture are being performed with constant rate up to an intensive increase of temperature of vapors. Then controlled feed of a cooling agent to a reverse condenser according to a temperature of a reflux is being performed. Temperature in the reactor had been stabilized, a second dose of the initiator, mixed with the dissolver, is being fed, and then the stabilization process is being going on up to breaking of copolymerization circuit, being detected according to a change of viscosity of the reaction mixture. EFFECT: enhanced accuracy of polymerization process controlling. 1 cl, 1 dwg
